my question how can data returned web service?

once posted can returned data this:

    bufferedreader in = new bufferedreader(             new inputstreamreader(conn.getinputstream()));     string inputline;     stringbuffer response = new stringbuffer();      while ((inputline = in.readline()) != null) {         response.append(inputline);     }     in.close();
